Customer challenge

 

For years, light in combination with temperature control and grading has been used in hatcheries to produce smolt all year round. But the industry has lacked optimized lighting systems and photoperiod protocols that would ensure improved production and welfare of smolts.

The right lighting 

 

Philips created an optimized lighting system for Sjøtroll Havbruk that offered more flexibility. This customized LED lighting solution for salmon hatchery applications delivered controlled ramp up and down, so that the light strategy could be changed according to the production planning.
